Im confused on how to solve this; A covered cubic tank 5.00 m by 5.00 m by 5.00 m is completely filled with water through a threaded hole in its lid. A hollow vertical pipe 5.00 m tall is screwed into the hole. The pipe has a cross sectional area of 8.00 cm². If the pipe is then filled to a height of 4.00 m, with an additional amount of water. what change in pressure, if any, will be read by a gauge in the side of the tank?

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min

amplitude

hope this
